Volume expansion failed any suggestions please
Hi Have a readynas 4200 v1 (4.2.31) which had one X-Raid volume from all 12 2Tb disks > 18Tb with two redundent disks. Worked fine. As disks died - usual rate - i replaced bays 1-4 with 3 Tb dri...
With RAIDiator-x86 4.2.x volume expansion cannot take place if the resulting volume capacity will be greater than 16TB. You clearly have hit that limitation.
You have two options:
- Do another factory reset and use RAIDar 4.3.8 to switch to Flex-RAID during the 10 minute countdown, and then using Frontview create multiple volumes (you may need to delete a volume before you can create the ones you want).
- Do an unsupported upgrade to OS6. OS6 does not have the 16TB volume expansion limitation, however in your model you are still limited to 2TB disks in bays 5-12.
If you don't expect to do any future expansion, or don't mind having to do another default if you do, you can just factory default and use XRAID to use all the drives' full capacity.
If you are doing a factory default, I highly recommend you move to OS6. In addition to solving the future expansion issue, you get a newer OS and you can move the drives to a native OS6 system if your 4200 dies.

That is incorrect. That is only true if all disks are of equal capacity, but the 4200 V1 is limited to 2TB disks in bays 5-12. So if you want to use e.g. 3TB (or even higher) capacity disks in bays 1-4 a factory reset won't be enough on its own to resolve the problem.
If you have 4 or more disks of a higher capacity than the smallest capacity disk then with X-RAID2 dual-redundancy there will be vertical expansion needed (you need at least four disks for each RAID-6 layer), however there is the 16TB volume capacity expansion limitation on RAIDiator-x86.
Upgrading to OS6 is the best solution in my opinion.
So incorporating the extra space on the larger drives is still considered an "expansion"? I didn't run my 4200V2 on OS4.2.x long enough to run into that situation.
Even more reason to go with OS6 and have a single volume.
